    A young plant growing from a seed is called a ...
    • A. 

      Seedling

    • B. 

      Seeding

    • C. 

      Seedlet

    • D. 

      Baby plant

  • 2. 
    We conducted some experiments: we put a pea seed in each of three pots; none of the pots had soil in them, they had a paper towel in the bottom. One pot we watered and put on the bench in the light. The second pot we watered, but kept in a dark cupboard. The third pot we kept in the light, but didn't water it.The pea seeds only sprouted in the first two pots. What can we infer (figure out) from this
    • A. 

      Pea seeds need light, soil and water (moisture) to sprout

    • B. 

      Pea seeds need light and soil to sprout

    • C. 

      Pea seeds only need light to sprout

    • D. 

      Pea seeds only need moisture to sprout

  • 3. 
    If we took three seeds and treated them differently as stated below, which would you expect to sprout? (They all get water and air).Seed A is kept at 50 degrees C Seed B is kept at room temperature (approx. 20 degrees C)Seed C is kept in the fridge at 4 degrees C
    • A. 

      Seeds A and B

    • B. 

      Seeds A and C

    • C. 

      Only seed C

    • D. 

      Only seed B

  • 4. 
    Which three things do seeds need to enable (let) them to sprout (put out plant parts)?
    • A. 

      Moisture, light and air

    • B. 

      Moisture, warmth and air

    • C. 

      Moisture, cold and air

    • D. 

      Light and air

  • 5. 
    How is a seed produced?[HINT: check the wording of the question carefully - always do this in a test. It is easy to misread a question and give the wrong answer]
    • A. 

      A seed is the product of pollen from the male part of a flower and the ovule inside the female part of a flower.

    • B. 

      Seeds are found inside fruit, for example there are seeds inside a tomato

    • C. 

      Seeds produce tiny little plants called 'seedlings'. This process is called 'sprouting'.

    • D. 

      Seeds make new plants and can be spread around by wind, water or animals. This is called dispersal

  • 6. 
    Tick ALL the statements that are involved in POLLINATION
    • A. 

      Pollen sticks to a bee's hairy sides

    • B. 

      The bee flies to another flower and the pollen rubs off on the sticky stigma (a female part) of the new flower

    • C. 

      The pollen grows down the style (long female part) of the flower (this forms the 'pollen tube')

    • D. 

      The pollen cell fuses with the ovule (egg cell) inside the ovary of the flower

    • E. 

      A seed forms inside the ovary of the flower, and the ovary matures into a fruit

  • 7. 
    What is is called when a pollen cell fuses with an ovule (plants) or a sperm cell fuses with an ovum (animal egg)?
    • A. 

      Mating

    • B. 

      Courtship

    • C. 

      Development

    • D. 

      Fertilisation

    • E. 

      Pollination

  • 8. 
    Which of the following is/are a method of POLLINATION? (There may be more than one answer).
    • A. 

      Wind (e.g. maize pollen blows over to the female flower parts)

    • B. 

      Water (e.g. coconuts drift to new islands and sprout there)

    • C. 

      Insect (e.g. bees transfer pollen to new flowers as they move around collecting nectar)

  • 9. 
    Once a seed has formed, plants have to have a way to spread the seeds away from them so that they have room to grow. Which of the following is/are a method of SEED DISPERSAL? (There may be more than one answer).
    • A. 

      Hooks (e.g. bidibids have tiny hooks on them and stick to passing animals or clothing like velcro, thus travelling long distances before falling off or being rubbed off)

    • B. 

      Wind (e.g. grass seed is very light and gets blown away from the parent plant in a strong breeze)

    • C. 

      Water (e.g. coconuts drift to new islands and sprout there)

    • D. 

      Ingestion (the fruit of a plant gets eaten - ingested- and the fleshy part of the fruit is digested, whilst the hard seed gets passed out in animal poo ready to grow in a new location - fertiliser included free!)

    • E. 

      Bee (bees put the seeds into the tiny sacks on their legs and carry them away to drop in new places)
